Putter head

Abstract

A putter head has a moment of inertia that can be adjusted easily by the golfer himself or herself. A putter head includes a body member having a face surface for hitting a ball and a back member turnably installed at the body member. The back member includes a plurality of movable parts, and the movable parts are turnably fixed to the body part. The movable part is turnably installed with one screw only.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a putter head.[0002]In a golf game, final putting often decides the game, and not only the golfer's capability of putting but also the performance and characteristics of a putter are one of the factors in deciding the game. Therefore, the adjustability of the performance and characteristics of a putter according to the physical condition of the golfer on the play day and the kind and condition of green lawn is advantageous to the golfer.[0003]For example, Japanese Patent Application Publication No. 2001-224718 describes a putter head formed by combining four parts to change the center of gravity of a putter head. The putter head is configured so that the four parts consist of a body, two wing parts located on both sides of the body, and a bottom part, and by fitting protrusions of the bottom part in grooves formed in the body and the wing parts, the parts are connected to each other. By forming the right and left wing...

AI Technical Summary

Benefits of technology

[0006]The present invention has been made to solve the above problems, and accordingly, an object thereof is to provide a putter head such that the moment of inertia thereof can be adjusted easily by the golfer himself or herself.

[0009]According to the present invention, as described above, the putter head includes the back member turnably installed to the body member, and the back member is turnably installed to the body member with one screw only. Therefore, the golfer himself or herself can adjust the moment of inertia of the putter head easily.

Problems solved by technology

In the configuration described in Japanese Patent Application Publication No. 2001-224718, however, although the center of gravity of the putter head can be changed greatly by changing the specific gravity of the right and left wing parts of the putter head, it is difficult to greatly change the moment of inertia of the putter head.

Also, in the configuration described in Japanese Patent Application Publication No. 2001-224718, the number of parts constituting the putter head is large, and therefore it is not easy to assemble a putter head having a strength capable of withstanding putting by using these many parts.

However, Japanese Patent Application Publication No. 2005-66249 does not especially describe that the moment of inertia of putter head is adjusted.

Also, in the configuration described in Japanese Patent Application Publication No. 2005-66249, the front half body and the rear half body are fixed with two bolts, so that this configuration is still insufficient for the golfer himself or herself to adjust the moment of inertia easily.
